Quoted from glpinball:
Funny story - so I rebuilt the flippers including replacing 3 of the 4 coils since they were very old and at least one had a stuck coil sleeve. First time doing this and soldering on a pinball game so that was interesting. But it worked in the end! Flippers are now amazing and I have hope I can actually hit some scores I see people getting on the game online. Before the flippers were so weak you had to use momentum to hit the bear ramp. But, as I was testing the flippers the ball would barely get out of the shooter lane at a full plunge. What the heck!!! Flippers have nothing to do with ball plunge! I'm looking at it, even removed the gate to eliminate that as being the problem. Checked the plunger, wondering if somehow its misaligned and hitting something as it goes in. Finally, go to set up a video and realize I can see metal on the plunger tip! Turns out at the exact same time I rebuilt the flippers, the tip of the rubber plunger cover broke off during my testing. Replaced it with an old one I had laying around and problem solved! Don't you love unrelated problems that come up during a fix?
Man, I’m getting my butt kicked on unrelated problems with my LOTR right now. Or, probably related I just can’t see how. The game I got the solonoid for the flipper had the wrong screws that you could tel the previous owner jammed in there and wasn’t holding the coil right. So all I did was replace the screws, but I must have bumped something because the next game the flipper was energizing up randomly, later locked on and blew the fuse, and now won’t flip at all even after going through it underneath to be sure the switches didn’t get bent. Now I’m tracing things back to the board ... and I’m not skilled with this level of diagnosis. Why did I have change the screws?!?
